This is for internal layer fast Absorption liquid, and it is suitable preventing from leaking, and therefore, according to what determine in ASTM D4772, internal layer should have at least 10% absorbance.Fabric in fact with Liquid Absorption in face liber rather than only liquid is held in the space between fiber, this is considerable.

Fig. 5 has shown a typical multilamellar fabric part 50, and it can be used for any clothes or clothes part, comprises aforementioned any embodiment.Fabric part 50 comprises 4 layers: ground floor or internal layer 100 have the first surface of body contact and have second surface; One second moisture absorption layer 200 has in abutting connection with the first surface of the second surface of internal layer 100, and second surface; The 3rd anti-liquid or blocking solution barrier layer 300 have in abutting connection with first surface and a second surface of the second surface of moisture absorption layer 200; In addition, may also comprise the optional precoat 400 with first surface and second surface for aesthetic reasons.If exist, the first surface of layer 400 is in abutting connection with the second surface of barrier layer 300.

Internal layer 100 can be to allow liquid to turn to any material of absorbed layer 200, even therefore also can keep relatively dry when liquid passes its surface.Can be by the dry internal layer 100 of several method.For example, be discharged into when liquid on the point source of inner surface (with body contacting surface) of internal layer 100, fabric can absorb liquid by large tracts of land it is distributed in the layer 200.In addition, layer 100 may be non-absorbent, and like this, most liquid is to transfer to layer 200, thereby makes layer 100 still not contain liquid and spot.So the spot in the layer 200 is also not obvious for dressing.

The material that is fit to body contacting layer 100 includes, but not limited to steep the fabric that fiber is made by following anti-soil own: polyolefin, polyamide, polyester and combination thereof.Discuss for convenience, the term " spot discharges, " that uses is referred to anti-soil stain material and discharges stain materials, comprise that those are processed into the material that the anti-soil stain maybe can discharge spot.In addition, layer 100 can comprise any suitable fabric, and this fabric has been processed into to have and can have discharged spot or anti-soil stain terminal (as Darlington listed in the Table A (Darlington) end).Layer 100 also can comprise the material that itself can discharge spot, for example microfibre or the microfibre mixture that constituted by different materials, and these materials can be processed into has bigger spot releasability.

In addition, or except above-mentioned, layer 100 may have a relative darker color, can help to cover up spot.

Moisture absorption layer 200 can comprise any material that can absorb the material of liquid and can discharge the liquid that absorbs at specified conditions (for example in the clothes cleaning process).The moisture absorption layer absorbability can surpass about 300 gram/square metre (gm/m ²); The bigger 800gm/m that surpasses ², still bigger above 1054gm/m ²In a preferred embodiment, the about 806g/m of the total absorptivity of wadding or liner ²-1178g/m ²

The suitable material that is used for moisture absorption layer 200 includes, but not limited to fabric or non-woven microfibre or polymerization knitted fabric; Fabric with hydrophilic fibers, absorption or super absorbing foams, fiber or powder formation.

On the other hand, owing to air gap or air pocket have any knitted fabric of savings liquid ability, knitted fabric, fabric, non-woven or the polymeric material of fluid-absorbing can both be used to moisture absorption layer 200.These materials include, but not limited to two-needle bar knit fabric, foam, non-woven fabrics etc.

In certain embodiments, moisture absorption layer 200 can comprise a knit fabric, and it is processed into has water-wet behavior.In addition, the yarn of making knit fabric can be processed into before knitting hydrophilic.In certain embodiments, yarn and knit fabric all can be processed into hydrophilic.

Perhaps, moisture absorption layer may be removed and abandon, and reduces or eliminates the demand of anti-soil stain.This discardable layer can comprise, as thin absorption or super absorbing foams, fabric non-woven fabrics or complex.

In addition, the free of contamination internal layer 100 that moisture absorption layer 200 can be had aesthetic feeling covers, and to cover some spots, this is still sightless concerning consumer.

Barrier layer 300 can comprise and anyly stop or at utmost reduce any material or the material compositions that liquid passes barrier layer that these materials can not cause adverse effect to sense organ and/or the feel of clothes.

Though a lot of material barrier layers 300 that are applied to capable of being combined, we have invented the method for the test percentage elongation of a uniqueness.We find that it is effective using fabric or the non-woven fabrics that can compare with the Darlington fabric in the Table A aspect the test of elongation rate result.

Owing to have moisture absorption layer 200, can absorb the liquid of specific quantity, the ability that barrier 300 is resisted hydrostatic pressing is moderate, this allows to exist more space of making aesthetic feeling.

For some suitable materials of barrier layer 300, include but not limited to be laminated to the fabric of polymeric membrane.Polymeric film thicknesses can less than or approximate 15 microns, more precisely can less than or approximate 10 microns, further definitely say less than or approximate 5 microns.The suitable material that is used for polymeric membrane includes but not limited to that copolyether ester, thermoplastic elastomer (TPE) (TPEs) are for example

Nylon and polyolefine material.If other soft thermoplastic elastomer has for enough pliabilitys and the pliability of making underwear, also may be used to.Polymeric membrane can be laminated into 2 layers or 3-tier architecture, maybe may be to hang over freely or be sewn between other layers, for example between absorbed layer 300 and aesthetic layer 400.A kind of suitable polymeric material is one can highly transmit moist monolithic polyurethane film, is sold with the model of TX1540 by the Omniflex company of Massachusetts Greenfield.

Other materials that are suitable for barrier layer 300 include but not limited to that 2 fold thin polymer film layer by layer, and it is protected by the other one deck that is not attached on the film, and this arrangement makes ready-made clothes feel more soft.Alternatively, this film/composite is subjected to hydrophobic (waterproof) and handles, thereby strengthens barrier properties and do not damage the feel of material.In another embodiment, thus barrier film or complex can stretch or heat and/or pressurize to be pressed into around layer and strengthen sensation.These stretchings or heating and pressurized treatments also have the advantage that causes gap, thereby strengthen breathability.

Other materials that are used for barrier layer 300 comprise hydrophobic fabric, and it may itself be hydrophobic or be processed into hydrophobic.The suitable fabric of handling with these hydrophobic cover layers includes but not limited to fine and close relatively fabric, non-woven fabrics or fabric.Suitable hydrophobic material for the treatment of fabric includes but not limited to polymer such as silica gel, polyurethane and combination thereof.In many examples, preferably use elastomeric polymer to be used for this purpose, as Lycra ( ) and their mixture.In certain embodiments, the knitted fabric of hydrophobic treatment, non-woven fabrics or textile material preferably contain microfibre because this can cause liquid infiltration the time path more tortuous.

If being used to form the material of barrier layer is non-woven fabrics, it is desirable using the melt-blown nonwoven cloth material, because it also provides the winding raod footpath for liquid.Multiple nonwoven, knitting or woven material also may close with the random layer array.Several or all precoats may be made by hydrophobic treatment or by hydrophobic material own.In the example, use this treated (non-film) material may provide than the better breathability of envelope barrier.A typical barrier layer is the elasticity melt-blown nonwoven cloth material of being made by copolyether ester, this copolyether ester and Kimberly-Clark (Kimberly-Clark) company before with

The trade name product sold similar.

In other embodiments, barrier layer 300 can be suitable comprises a microporous polymer membranes.Suitable microporous polymer membranes includes but not limited to polyurethane film, tool tetrafluoroethene (PTFE) film, polyolefin film and compositions thereof.Suitable microvoid polyurethane film is sold by the Porvair PLC of Britain Norfolk.The product of the obtainable micropore tetrafluoroethylene that other are suitable is by name

(the W.L.Gore﹠amp of Delaware State Newark; Associates company).This microporous membrane can be used for the combination of any precoat, but can be stacked also not stacked, and can pass through hydrophobic water-proofing treatment, thus perhaps fill as the material retaining hole of oil not contaminated.

Various materials can be used as optional aesthetic layer 400.The example of material that is fit to layer 400 include, but are not limited to lace, silk, chiffon, cotton, terylene, nylon,

Deng and their mixture and compositions.If desired, can fabric is painted, spray printings etc. also can be processed into and have any functional character described here.
